D-Series Industrial Cooling Fans

High efficiency, low noise cooling fans

The D-series has been developed and proven to be the best combination of performance, reliability and price for operation in air-cooled condensers and cooling towers. It is available in a wide range of diameters with different blade profiles and blade arrangement to best fit the specification of each project.


Key features

  • Diameters from 26 feet (7925mm) to 38 feet (11582mm)
  • Six blade profiles (DNF, DLF and DVF – DNM, DLM and DVM)
  • DVF and DVM feature double hub plate (for ACC applications)
  • Between 5 and 11 blades manufactured with an integral shaft
  • Operating temperatures from -20°C (-4°F) to 65°C (149°F) as standard - extendable up to 120°C (248°F) on request.


  • A wide range of flows can be handled while meeting the required noise level

  • Integrated shaft eliminates concentrations of stress at the mechanical joints giving greater durability

  • Reliable performance regardless of external environmental conditions

Range graph


The D-Series is mainly used within Air Cooled Condensers, but can also be deployed within field erected Cooling Towers. With its larger diameters, it is typically used within industries with significant cooling requirements such as power and large scale energy facilities. Due to its diameter range it is not typically used within Air Cooled Heat Exchangers.
